GAS-SCRUBBING APPARATUS.

Be it known that I, JOSHUA J. NIX, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Gas- Scrubbing Apparatus.

.of which the following is a full, clear, and

exact description.

The object of the invention is to provide a new and improved scrubbing apparatus, more especially designed for purifying gas from crude oil.

The invention consists'of novel features and parts and combinations of the same,

.Fig. 1; Fig. 3 is aplan view of the same.

The scrubber E is constructed in detail as follows, special reference being had to Figs. 1, 2 and 3. The scrubber E is divided. into a plurality of compartments S, S S S, S

and S, of which the compartment S is the entrance compartment and is provided with a downwardly-extending pipe T, connected at its upper end with the duct 1), so that the cooled gas passes by way of the pipe T into the entrance compartment S, the gas being further cooled by'a spray of water issuing through a nozzle U arranged within the pipe T and connected by a pipe U having a valve U with a water distributing chamber U connected by a pipe U with a suitable water supply. Pipes T, T T T and T connect the several compartments with each other, and each of the said pipes is provided with a distributing nozzle U having its pipe U connecting with the distributing chamber U The last compartment S is connected with the pi e F leading to the gas holder, engine or ot er machine inwhich the is used.

The entrance compartment S is provided with -two overflow pipes V-and V, the pipe V being arranged below the lower end of the pipe T and the pipe V being arran ed above the end of the pipe T, and the overiiow pipes Specification of Letters Patent.

V and V lead to a common pipe V discharging into a water chamber connected by an overflow pipelV with a tank 7 from which leads an overflow pipe W to a sewer or other suitable place of discharge. The ovcrllow pipes V and V are provided with valves V, V, to permit of regulating the level of the water accumulating in the tank S and discharged by the nozzle U.

Thus when the mlve V is closed, the water level in the compartment S is above the lower end of the pipe T and consequently a water seal provided for this pipe T, to retain the gas in the duct 1) and the retort (l a suilicicnt length of time to insure the production of a high quality of gas. lVhen the valve Vf is closed and the valve V is opened then the level of the water in the compartment Sis below the lower end of the pipe T, and. consequently the producer gas can more freely pass into the compartment S without hindrance of the water. The gas passes from the compartment S by way of the pipe T into the compartment S and by way of the pipe T into the compartment S and so on until the gas finally reaches the exit S connected with the pipe F. Now the gas in its passage through the several pipes T, T, T", T, T" and'T" is subjected to a water spray, and consequently the gas is washed and the solid carbon particles are precipitated, the gas when finally reaching the pipe F being in a. thoroughly cooled clean state.

The compartments S, S, S, Sj and S are provided with overflow pipes \V" discharging into the tank W, as indicated in Fig. l. liy having the valves lb, the amount oil. \valcr passing into the nozzles to be sprayed can bc rcgulalcd to a niccty;

The operation is as follows: The gas is cooled and passes into the scrubber l) and through the several compartmcnts thcreo'li in thc manncr previously described, lo wash the gas. lly having the water seal for the pipe T, it is evident that the gas is retarded in its travel to the rclorl (l and the duct l),and islhus propcrly lixcd,and a uniform itllllflll'illlll'c is maintained to avoid local, intense and dcstrluztive hcat. By subjecting the gas to successive sprays of water in the scrubber E, .the gas is thoroughly washed and finally passes by way ot the pipe 1 into a gas holder or to the engine or other machine, to be used therein in the usual manner for producing power.

her, pipes connecting one compartment With Having thus described my invention, it claim as new and desire to secure by Letters Patent:

1. A scrubber comprising an annular casing provided with radial partitions dividing the easing into a plurality of compartments, one of said compartments being an entrance compartment and having a communication with a source of gas supply and an adjoining compartment being the exit compartment and delivering the gas from the scrubthe' other and having their discharge opening downward, a water spray nozzle in each pipe, the said entrance compartment being adapted to contain a fluid in the bottom thereof and pines leading from said compartment atdihercnt levels, one above and one below the opening of the communication with the source of gas supply, and valves in the pipes for the purpose set forth.

2. A scrubber having an entrance c0mpartment, an exit. compartment, a plurality of compartments intermediate the said entrance and exit compartments, apipe extend ing into the said entrance compartment and connected with a gas supply, pipes connecting one compartment with the other, water-spraying nozzle in each pipe, the entrance compartment being adapted to contain a fluid, and means for regulating the level of the fluid whereby to form a water seal for the pipe extending into the entrance compart-merit or to leave said pipe open.

3. A scrubber having an entrance c0m'-- I partment, an exit compartment, a plurality of compartments intermediate the said entrance and exit compartments, a pipe extending into the said entrance compartment and connected with a gas supply, pipes connect ing one compartment with the other,a Waterspraying nozzle in each pipe, a double water overflow :tor the said entrance compartment,
